Now the Symbol

Analayze

The hatched background shows a heavily rainy storm. The hurricane is clearly shown at the top-left corner which tends to reach the centre of the rectangle , so i hope it clearly shows the movement. And the spiral-flying fishes represent a school of fish chasing the clouds in the sky, as the warmer earth is evaporating the water faster.
This is the final Symbol representing tornado.

Here is how it's done.

1. This spiral cloud is created to be disorted to a hurricane shape later. Pen tool was used.

2. The next step is to disort the spiral cloud using the Roughen filter.

3. Now is time to twist the cloud to build a hurricane figure just by using Twirl filter.

4. To show the flying fishes over the clouds it is easy to draw one fish and copy ,resize and rotate to follow a spiral path using the pen tool. The stroke is to be changed to the marker tool found on the brush panel.

5. The final step is to create the rainy background. To do so, a rectangle with the navy-blue fill is needed. After that the hatch-effect filter is all need to be done.

Inspiration and sketches

These are the two images which gave me the whole idea. The first one which is called the "school of fish" gave me the idea of floating fishes in the sky , as the sun glow is clear in the picture. Higher tempreture leads to more evaporation and heavier clouds. As the matter of fact these creatures would seek for water into the sky. The second picture ,which is an eye of an hurricane ,is one of the effects of the global warming.

Here in the sketches , these two factors are clear. Figure 1 and 2 are views from earth to an eye of an hurricane.
Figure 3 is my preliminary idea of fishes in the sky which also represent the clouds.

The whole view would be a mixture of these three figures which is shown in figure 4. The orange color is the sun and the blue-green color used to show the fishes which represent the clouds.

Tornado

Tornado and the climate change.

As we are currently experiencing the earth getting warmer, it is clear that this change is affecting every natural phenomenon such as tornadoes.

However there are few evidence that demonstrate the relation between the Global Warming and the increase in the tornadeos, the recent Nasa study shows that as the temperature rise stronger tornadoes may occure.

Base on this study, warmer climate by just 5 degrees will decrease humidity and vigorous tornadoes will be formed in higher levels than sea. This means that, however the number of tornadoes will be decreased but we would have much stronger tornadoes. And drier climate increases the risk of fire while lightning.

Intruduction

What is Global Warming?

Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate forever.




What are the main causes?

• Natural Causes

Realising methane gas from arctic.There is some kind of bacteria living in warmer soils of arctic which release methane gas into the atmosphere.Methane is one of the strongest greenhouse gases.

Naturaly cliamte changes over time and this change last for approximately 40,000 years

• Man-made Causes

Population,burning fossil fuels,Mining which fluxes methane gas into the atmosphere.Methane exists in the ground.In the process of digging the mines for coal,... methane is released.
